Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer Gummiformdichtung mit einer metallischen Einlage zur Versteifung, die von einer gummielastischen Schicht umgeben ist.The invention relates to a method for manufacturing a molded rubber seal with a metallic insert for stiffening by a rubber-elastic layer is surrounded.
Solche Gummiformdichtungen werden insbesondere in Brennkraftmaschinen als Ölwannendichtung, Zylinderkopf-Haubendichtung, als Dichtung für ein zwischen Ölwanne und Motorblock angeordnetes Schwallblech oder dgl. eingesetzt.Such molded rubber seals are particularly in Internal combustion engines as an oil pan gasket, cylinder head cover gasket, as a seal for between the oil pan and engine block arranged baffle or the like. Used.
Gummi hat die Eigenschaft, nach dem Vulkanisieren stark zu schwinden. Um Ablöseerscheinungen zwischen Gummi und Metall aufgrund dieses Gummischwundes vorzubeugen, hat man bisher Gummi und Metall mittels eines Haftvermittlers miteinander verbunden.Rubber has the property of being strong after vulcanization to wane. To peel between rubber and To prevent metal due to this rubber shrinkage Previously rubber and metal were used with an adhesion promoter connected with each other.
Bei bekannten Verfahren der eingangs beschriebenen Art zum Verbinden eines gummielastischen Materials mit Metall wird jenes Material an der Grenzstelle zwischen Gummi und Metall so modifiziert, daß eine haftvermittelnde Zwischenschicht entsteht.In known methods of the type described above for connecting a rubber-elastic material with metal is that material at the boundary between rubber and Modified metal so that an adhesion-promoting intermediate layer arises.
Mit dieser Maßnahme soll eine hohe Bindekraft bzw. gleichmäßige Festigkeit geschaffen werden (DE-OS 19 05 967, DE-OS 20 30 346).With this measure a high Binding force or uniform strength can be created (DE-OS 19 05 967, DE-OS 20 30 346).
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs beschriebenen Art anzugeben, das eine einfachere Herstellung der Gummiformdichtung ermöglicht und gleichwohl eine im Betrieb zuverlässige Dichtung ohne Ablöseerscheinungen zwischen der gummielastischen Schicht und der metallischen Einlage ergibt.The invention has for its object a method of the type described at the beginning, which is a simpler Production of the molded rubber seal enables and nevertheless a reliable seal in operation without Detachment between the rubber-elastic layer and the metallic insert results.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die gummielastische Schicht ohne Haftvermittler direkt auf die metallische Auflage aufgebracht und vulkanisiert wird.To achieve this object, the invention provides that the rubber-elastic layer without adhesion promoter directly applied to the metallic surface and vulcanized becomes.
Durch Vermeiden des Haftvermittlers ist dessen aufwendige Aufbringung auf die zu verbindenden Flächen und damit ein kostspieliger Schritt bei der Herstellung eingespart. Versuche bei der Anmelderin haben gezeigt, daß gleichwohl eine über die gewünschte Lebensdauer der Gummiformdichtung zuverlässige Funktion gewährleistet ist.Avoiding the adhesion promoter is time-consuming Application to the areas to be connected and thus costly manufacturing step saved. Tests by the applicant have shown that nonetheless one about the desired service life of the molded rubber seal reliable Function is guaranteed.
Besonders gut haftet eine gummielastische Schicht nach den Feststellungen der Anmelderin auf einem phosphatierten Blech als metallische Einlage.A rubber-elastic layer adheres particularly well according to the applicant's findings on a phosphated sheet as a metallic insert.
Ferner hat sich nach den Feststellungen der Anmelderin bewährt, wenn die gummielastische Schicht aus einem Polyacrylat (ACM) oder aus einem Ethylen-Acrylat-Kautschuk (EAM) besteht.It has also proven, according to the applicant's findings, if the rubber-elastic layer consists of a polyacrylate (ACM) or an ethylene-acrylate rubber (EAM) .
Beispiele von mit dem Verfahren nach der Erfindung hergestellten Gummiformdichtungen sind im folgenden anhand von Zeichnungen dargestellt. Es zeigen:Examples of using the method according to the invention Molded rubber seals are as follows represented by drawings. Show it:

Fig. 8 bis 15 in Draufsicht, Stirnansicht und Schnitt darstellungen eine Zylinderkopf-Haubendichtung nach der Erfindung. Fig. 8 to 15 in plan view, front view and sectional views of a cylinder head cover gasket according to the invention.
Die in den Fig. 1 bis 3 gezeigte Ölwannendichtung für die Brennkraftmaschine beispielsweise eines Kraftfahrzeuges weist eine Blecheinlage 2 aus einem phosphatierten Blech auf, das von einem gummielasti schen Material 4, beispielsweise einem Polyacrylat (ACM) oder einem Ethylen-Acrylatkautschuk (EAM) 4 umgeben ist. Das gummielastische Material 4 ist ohne Haftvermittler auf das Blech 2 aufgebracht und damit vulkanisiert.The oil pan seal shown in FIGS . 1 to 3 for the internal combustion engine, for example of a motor vehicle, has a sheet insert 2 made of a phosphated sheet, which is surrounded by a rubber-elastic material 4 , for example a polyacrylate (ACM) or an ethylene-acrylate rubber (EAM) 4 is. The rubber-elastic material 4 is applied to the metal sheet 2 without an adhesion promoter and thus vulcanized.
Die geschlossene Dichtung weist in regelmäßigen Abständen Durchgangslöcher 6 zum Durchlassen von Schrauben zum Verbinden der nicht gezeigten Ölwanne mit dem nicht gezeigten Motorblock der Brennkraftmaschine auf. Um diese Löcher 6 ist das Material der Blecheinlage in einem kombinierten Ziehen und Kaltfließpressen zu einem buchsenförmigen Verpressungsbegrenzer 8 herausgezogen, dessen Länge 1 größer als die Stärke s der Blecheinlage 2 ist. Die Wandstärke t des Verpressungsbegrenzers 8 ist größer als die Stärke s der Blecheinlage 2.The closed seal has through holes 6 at regular intervals for the passage of screws for connecting the oil pan, not shown, to the engine block, not shown, of the internal combustion engine. Around these holes 6 , the material of the sheet insert is pulled out in a combined drawing and cold extrusion to form a bush-shaped compression limiter 8 , the length 1 of which is greater than the thickness s of the sheet insert 2 . The wall thickness t of the compression limiter 8 is greater than the thickness s of the sheet metal insert 2 .
Die Länge 1 läßt sich genau auf einen gewünschten Wert kalibrieren. Die Stirnflächen 10 und 12 an den beiden Enden des buchsenförmigen Verpressungsbegrenzers 8 sind unterschiedlich groß bemessen, und zwar in Anpassung an die Werkstoffe der miteinander zu verbindenden Bauteile (Ölwanne und Motorblock). Die größere Fläche 12 ist der gewöhnlich aus Aluminium bestehenden Ölwanne zugewandt, die im Vergleich zum Grauguß des Motorblocks nur eine kleinere zulässige Flächenpressung verträgt.Length 1 can be calibrated exactly to a desired value. The end faces 10 and 12 at the two ends of the bush-shaped compression limiter 8 are dimensioned differently, specifically to match the materials of the components to be connected (oil pan and engine block). The larger surface 12 faces the oil pan, which is usually made of aluminum and can only tolerate a smaller permissible surface pressure compared to the gray cast iron of the engine block.
Die Länge 1 ist ein Maß für die Verpressungsbegrenzung. Bis zur Anlage an die Verpressungsbegrenzer 8 können die die Löcher 6 durchsetzenden Schrauben unbedenklich, d.h. ohne genau bemessenes Drehmoment, angezogen werden, wonach dann die Dichtung und damit das gummielastische Material einer genau definierten Pressung unterzogen ist. Length 1 is a measure of the compression limitation. Up to the contact with the compression limiter 8 , the screws passing through the holes 6 can be tightened safely, ie without a precisely measured torque, after which the seal and thus the rubber-elastic material is subjected to a precisely defined pressing.
Bei der Zylinderkopfhaubendichtung nach den Fig. 4 bis 7 sind der Einfachheit halber gleiche bzw. funktionsgleiche Teile mit gleichen Bezugszeichen belegt.In the case of the cylinder head cover gasket according to FIGS. 4 to 7, for the sake of simplicity, identical or functionally identical parts are given the same reference numerals.
Der Unterschied bei der Ausbildung dieser Zylinder kopf-Haubendichtung im Vergleich zur Ölwannendichtung nach den Fig. 1 bis 3 besteht hauptsächlich darin, daß die Blecheinlage 2 nur teilweise von dem gummielastischen Material 4 umgeben ist (s. die Fig. 5 bis 7). Die übrigen Merkmale sind gleich wie bei der Ausführung nach den Fig. 1 bis 3.The difference in the design of this cylinder head cover seal compared to the oil pan seal according to FIGS . 1 to 3 is mainly that the sheet metal insert 2 is only partially surrounded by the rubber-elastic material 4 (see FIGS . 5 to 7). The remaining features are the same as in the embodiment according to FIGS. 1 to 3.
Insbesondere Fig. 7 veranschaulicht, daß die Blecheinlage 2 lediglich am Außenrand von dem gummielastischen Material 4 umgeben zu sein braucht.In particular, FIG. 7 illustrates that the sheet-metal insert 2 need only be surrounded by the rubber-elastic material 4 on the outer edge.
Eine solche Konstruktion wird beispielsweise auch bei der Abdichtung eines Schwallbleches (nicht gezeigt) gewählt, das zwischen der Ölwanne und dem Kurbelgehäuse des Motorblocks bei bestimmten Motorkonstruktionen eingesetzt wird.Such a construction is also used, for example when sealing a baffle (not shown) chosen between the oil pan and the crankcase of the engine block at certain Motor constructions is used.
Es sei darauf hingewiesen, daß das gummielastische Material bei beiden ausgeführten Dichtungen innen und außen mit umlaufenden Rippen 14 versehen ist, welche die Dichtwirkung bestimmende Preßdruckspitzenwerte in montiertem Zustand ergeben. It should be noted that the rubber-elastic material is provided with circumferential ribs 14 on the inside and outside of both seals, which result in peak press pressure values determining the sealing effect in the assembled state.
In den Fig. 8 bis 15 ist eine Ausführung einer Zylinderkopf-Haubendichtung einer Brennkraftmaschine gezeigt, die an einem Ende einen Halbbogen 18 (Fig. 8, 9) aus gummielastischem Material aufweist, der in eine Nut des vorderen Nockenwellenlagerbockes (nicht gezeigt) eingreift und dort abdichtet. An dieser Stelle ist die Blecheinlage 2′ ausgespart. Am hinteren Ende des Zylinderkopfes (nicht gezeigt) befindet sich eine halbrunde Bohrung, die zur Bearbeitung der Bohrungen der Nockenwellenlager erforderlich ist. Diese wird durch ein halbmondförmiges Formstück 20 (Fig. 8, 9, 14, 15) ausgefüllt, das vorteilhaft als Bestandteil der Zylinderkopfhaubendichtung ausgebildet ist. An dieser Stelle kann die Blecheinlage 2′ durchlaufen, wie in Fig. 14 zu erkennen ist.In FIGS. 8 to 15, an embodiment is shown of a cylinder head cover gasket of an internal combustion engine having at one end a semi-arch 18 (Fig. 8, 9) of rubber-elastic material (not shown) in a groove of the front camshaft bearing block engages and seals there. At this point, the sheet insert 2 'is omitted. At the rear end of the cylinder head (not shown) there is a semicircular hole that is required to machine the holes in the camshaft bearings. This is filled by a crescent-shaped fitting 20 ( Fig. 8, 9, 14, 15), which is advantageously designed as part of the cylinder head cover gasket. At this point, the sheet insert 2 'can run through, as can be seen in Fig. 14.
Beim Füllen des Spritzgießwerkzeuges zu Beginn des Vulkanisationsprozesses auf einer Spritzgießmaschine wird die Gummimischung in einzelnen Bereichen in den formgebenden Bereich des Werkzeugs eingespritzt. Wegen der in den Formhohlraum eingelegten Blecheinlage 2′ fließt Gummimischung sowohl ober- als auch unterhalb der Blecheinlage, wobei sich leicht ein unterschiedlicher Druck aufbauen kann. Um einen Druckausgleich auf beiden Seiten der Blecheinlage zu schaffen, sind in Abständen Löcher 22 in die Blecheinlage eingestanzt (Fig. 12, Schnitt C-C in Fig. 8). Damit das Blech in der vorgegebenen Lage in der Spritzgießform gehalten und nicht durch einseitigen Druckaufbau verschoben werden kann, werden im Werkzeug Stifte 24 gesetzt, die das Blech im Werkzeug zentrieren (Fig. 13, Schnitt D-D).When the injection molding tool is filled on an injection molding machine at the beginning of the vulcanization process, the rubber mixture is injected in individual areas into the shaping area of the tool. Because of the inserted in the mold cavity sheet insert 2 'flows rubber mixture both above and below the sheet insert, which can easily build up a different pressure. In order to equalize the pressure on both sides of the sheet insert, holes 22 are punched into the sheet insert at intervals ( FIG. 12, section CC in FIG. 8). So that the sheet is held in the predetermined position in the injection mold and cannot be shifted by one-sided pressure build-up, pins 24 are placed in the tool, which center the sheet in the tool ( FIG. 13, section DD) .
